CuBr (s) ⇌ Cu+ (aq) + Br- (aq)
Cu+ (aq) + 2 NH3 (aq) → Cu(NH3)2 (aq)
CuBr(s) + 2 NH3 (aq) ⇌ Cu(NH3)2 (aq) + Br- (aq)
Copper(l) ions in aqueous solution react with NH3(ag) according to
Cu+(aq) + 2NH3(aq) → Cu(NH3)2+(aq) Kf = 6.3 x 1010
Calculate the solubility (in g • L-1) of CuBr(s) (Ksp = 6.3 x 10-9) in 0.88 M NH3(aq).
